I have 2 registry cleaners that find alot of errors (usually deleted files w/ registry entries pointing nowhere because of it) and I delete them, so I suppose this fragments te registry. I have never once defragged the registry in my life and I'm wondering 1. Is it safe to do? 2. will I see a performance gain (anything to 1 more FPS in a game to faster load/boot times) 3. What is the name of a good registry defragger?
